Customised Cranioplasty Implant for Decompressive Craniectomy Patients -A Technical Note.

Cranioplasty is a commonly performed procedure following decompressive craniectomy. The patients are usually young earning persons and increasing cost of treatment is difficult to bear especially in low and middle income countries. A variety of options are available for cranioplasty ranging from autologus bone graft to xenograft and synthetic materials. Presently the autologous cryopreserved or subcutaneously preserved bone graft is considered as preferred choice but is has its drawback of bone resorption and infection . Custom made titanium implants and Polyetheretherketone (PEEK) implants using 3D printing technologies are also being used but its use is limited because of its high cost and lack of availability of this these technologies in the developing world which have maximum number of such cases. The authors present an easy and low cost technique for making customised cranioplasty implant by Polymethylmethacrylate (PMMA) using the craniotomy bone flap of the patient as a template.
